Hi Jackie
I am sorry to hear your mum is in dialysis. Yes, I have been lucky in that I have been able to recover much of my kidney function from the 11% when I was diagnosed in August 2009. Being really honest this has been a combination of good luck and the implementation of a long term strategy to regain health. I cannot reply to you quickly as it will take me a while to write down my approach (I am a carer as well as having myeloma and this takes much of my time). I will respond fully within the next couple of days.
Just a quick note on fluids. Some of us on diagnosis have very poor kidney function but our kidneys still pass significant amounts of urine (mostly water). This means it is both possible and advisable to flush the kidneys by drinking lots of water. However, when all the tubes (nephrons) are blocked the kidneys cannot get rid of the water and it builds up in the body. It is for this reason your mum is limited to 1 litre a day. More on this later.
Kind regards
Martin
PS My response will be too long to post here. If you can text me an email address to 07968483337 I will respond fully with my long-term renal strategy.
